摘要
本文根据６年定位研究结果，讨论了北温带山溪激流植物群落生态学方面的问题。文中分析了激流群落的种类组成、数量特征、外貌、结构、分布格局、动态与功能等。根据种－面积曲线确定样地最小面积；分析群落自然高度与绝对高度的相关性；探讨了群落的垂直分层与水平镶嵌；划分了群落的生态种组和生态差型；建立了群落的物候型谱和生物量成层模型；阐述了群落的建成过程和演替类型；最后，按照水毛茛对于扰的适应机制分析了其繁殖策略；提出了内陆黑潮并分析了其对群落演替所发生的影响。
The community ecology of the torrentiai plants was investigated in a stream ofNorth Temperate from 1986 to 1991.Some community parameters such as speciescomposition,quantitative features,physiognomy,structure,distribution pattern,dyna-mics and function werePresented.The minimum area was determined as being 5m￣2from the species-area curve。The ralationships between the natural height and theabsolute height of Ranunculus bungei was significantly correlated.Furthermore,thecommunity exhibited a clear pattern of vertical stratification and horizontal mosaic. The phenological spectrum and biomass models were also established。In light ofthe resistance of the plant to interference,the reproductive strategies of the speciesagainst adverse conditions were discussed,and so was the Inland Kuroshio in rela-tion to its effect on the community.
